Cancer screening is a process that helps detect cancer early, often before symptoms appear. It involves tests and exams that can identify cancer or precancerous conditions in individuals who may not yet feel unwell. Common screening methods include mammograms for breast cancer, colonoscopies for colorectal cancer, and Pap tests for cervical cancer. Early detection can lead to more effective treatment and better outcomes. Regular cancer screenings are important for people, especially those at higher risk due to factors like age, family history, or lifestyle. By participating in these screenings, individuals can take proactive steps towards their health and potentially save lives through early intervention.
